More fun with -Xmigration.
to BufferLike (++ and similar now create a new collection.)
Removed MapLikeBase. Annotated all the methods in mutable.{ Map, Set }
which mutated in-place in 2.7 to note that they create new
collections, and implemented same.
At this point the only +/- like method which mutates in place which I am
aware of is BufferLike.+ (see source comment for my observations.)
Also tweaked some collections return types as necessitated by these
changes, such as mutable.Set.clone() now returning "This" rather than
mutable.Set[A].
References #3089, closes #3179. Review by odersky.
